Especially all existing LED nightlight has big problem that LED unit have too strong brightness to be seen by viewer on the narrow viewing angel only. It looks like spot-light effects (super bright on small area). The current invention use multiple (more than one) optics means to make a big improvement of this spot-light to linear or area brightness out of the said LED unit to make the said spot-light effects change to nice looking like the fluorescent tube effects. It is very difficult to use only one optics means to make the strong spot-light LED unit(s) to nice and warm light effects to be seen by viewer. This is a big improvement of the said LED night light.

The current invention further to add some other arrangement such as reflector(s), bubble(s), lens within the any of the optics means to increase the effects to make the narrow viewing angle light beams out of the said LED(s) to linear or area light effects.

Furthermore, the current invention solved the LED Night light problem because the most popular Night light at market place. The most popular night light length around 88 mm+/−50 mm (with base), The lens height around 60 mm+/−30 mm (without base). The height from the wall outlet cover around 35 mm+/−15 mm (from outlet cover surface): The LED unit if place on the same location of the outlet cover surface, The distance from wall to outside of lens will be only less than 35 mm+/−15 mm too short to make the spot-light LED's into a surface or area photometric or lighted area so this convention use the 2 optics means to get the good surface or area lighted effect. This will be the best because LED night light power consumption fall within the 0.3 W+/−100% per LED range. The bulb Night light power consumption is fall within 4 Watt+/−50% per bulb. So the LED night light will have a big power saving for the electricity and money for monthly bill for consumer.

The current invention not only make a simple function LED night light, but it is appreciated to use this excellent light performance skill incorporated with the other function to build with the simple function LED Night light. The LED night light with more than one function can be add the function may selected form outlet adaptor, motion sensor, PIR sensor, air freshener, 2^(nd) light, bug repellent, sonic repellent or the any combination so all the LED night light can be have all such nice light performance with more than single functions.

DETAIL DESCRIPTION

From FIG. 1, show the LED night light with more than one optics means which has a base housing (100) which has space to arrange circuit board (400) within to make the home electricity from prong means (500) to said circuit board to turn on the said LED (401) and (402) under predetermined time, period, duration, functions. The said LED units (401) (402) on different locations for different illumination purpose. The co-pending filing U.S. patent application of Ser. No. 11/255,981, Multiple light source Night Light has details description for the two light sources for the said night light, so we do not discuss more details here.

The 1^(st) LED (401) may have single color or multiple colors with 2 legs up to multiple legs to connect with the said circuit board (400). The 2 legs LED unit normally has 1 color. The 4 legs LED unit normally has 3 colors with its leg to connect with said circuit board to get specified color individually and one leg to is for common leg to connect the said circuit board so can get desired color incorporated with integrated circuit (hereafter as IC). The said LED unit may have conductive legs or said the poles, or the said electrodes in variety shape such as conventional types may selected from group combination including chip type, regular type, surface mounting type (hereafter as SMT type), dice type from marketing place.

The 1^(st) LED unit face the top and majority of the LED's light beams emit to the said 1^(st) optics means (300). The 1^(st) LED's light beam will traveling within the 1^(st) optics means and allow the viewer to see the light beam from everywhere of the said 1^(st) optics means (300). This arrangement to make the LED's spot brightness become a tube brightness. The viewer see a lighted tube like a fluorescent tube because this 1^(st) optics means to change LED's spot-brightness into a linear tube brightness though this 1^(st) optics means. However, the said 1^(st) optics means also has its limitation such as the length of the optics means can not too long, the diameter can not too bigger than the LED unit's diameter. If the length of the optics means too long, the viewer will see the brightness is very bright on the LED end and the brightness on the other end is very dim. Hence, The length of the optics means need to do properly so can let viewer to see very nice photometric brightness of said the optic means. Because these limitation so we need to add the 2^(nd) optics means to make the best light effect of said the LED night light.

From FIG. 1, the 1^(st) optics means (300) has proper length in order to make the brightness of everywhere as close as possible to viewer. In order to get more perfectly light effect so incorporate with a top-tip which in a dome shape (301) which will make all light beams to hit the dome (301) and reflect back to 1^(st) optics means (300) to make top-end of the 1^(st) optics means have as close as brightness as the low-end of the 1^(st) optics means. Furthermore, the 1^(st) optics means can have some other arrangements within the 1^(st) optics means which may add the air-bubbles inside to make light beam to hit it and reflect to other directions. It also can add some reflective reflectors to make the same functions. All equivalent skill from conventional market still fall within the same scope so the current discussion and preferred embodiment should not treat as limitation of the current invention.

From FIG. 1, The light beams from LED's (401) spot brightness though a 1^(st) optics means (300) become to a linear light pattern with other treatment of dome tip (301) and inner air bubbles (302) to get 1^(st) optics means (300) as a super bright lighted tube. However, the 1^(st) optics means (300) the length is short (because too long will have problem for brightness different on top and bottom) and the diameter is too small (If diameter is too big than the LED's diameter, the light only cover certain area of the said 1^(st) optics means, so the diameter should be match the LED's diameter and distance of the LED to optics means base), so it can not meet consumer requirement for nice appearance, so we need to add 2^(nd) optics means (200) which in a lens design.

From the market requirement and consumer expectation, the LED night light should be have similar outer shape as traditional bulb night light. Hence, The said 2^(nd) optics means (200) preferred to have the lens design to surround the 1^(st) optics means (300). The 2^(nd) optics means in a lens design which may have different optics arrangement on it surface or its body such as ribs, groove, dots, convex lens, concave lens, different thickness, reflectors, air-bubbles, liquid, miniatures, holes, windows, stencils to make the inner 1^(st) light mean's light be seen by viewer with nice and elegant light effect. not shown)

From FIG. 2 of the drawing, The base housing (01) has hole (05) for inner LED1 (06) and 1^(st) optic means tube (09) to installation and make the light beam from LED1 (06) to emit to the said 1^(st) optics means (09). The base housing (01) has the 2^(nd) hole (08) for inner LED2 (08) and hole's lens (not shown) to allow the light beam from LED2 (08) to emit out to the desired location though the hole's lens such as the floor so can make the sufficient brightness to the floor during the dark area.

From FIG. 2 show the circuit board (04) are fit within the base housing (01) to allow the home electricity connect to the LED night light's prong means (02) to deliver the current to the circuit board (04) and offer the right current to the said LED1 (06) and LED2 (07) to turn on under predetermined time with desired function, duration, brightness, functions. The circuit board (04) incorporated with electric components may selected from group combination from resistor, capacitor, switch means, sensor means, diode, inductor, transformer, or any available components suit for electric circuit drive LED(s) for predetermined functions, duration, time, effects. The 1^(st) optics means (09) have a groove rings to all the 2^(nd) optics means (03) to clip on. The 1^(st) optics means (09) have a dome top to make the light beam to reflect all light beams back to the 1^(st) optics means as much as possible. The 1^(st) optics means has plurality of the air bubbles within its body to make more eye-catching reflective light spot to increase light effect and value.

The 2^(nd) optics means (03) in a lens design which may have different optics arrangement on it surface or its body such as ribs, groove, dots, convex lens, concave lens, different thickness, reflectors, air-bubbles, liquid, miniatures, holes, windows, stencils to make the inner 1^(st) light mean's light be seen by viewer with nice and elegant light effect. not shown). The most popular night light length around 88 mm+/−50 mm (with base), The lens height around 60 mm+/−30 mm (without base). The height from the wall outlet cover around 35 mm+/−15 mm (from outlet cover surface).

The LED unit if place on the same location of the outlet cover surface, The distance from wall to outside of lens will be only less than 35 mm+/−15 mm too short to make the spot-light LED's into a surface or area photometric or lighted area so this convention use the 2 optics means to get the good surface or area lighted effect. This will be the best because LED night light power consumption fall within the 0.3 W+/−100% per LED range. The bulb Night light fall within 4 Watt+/−50% per bulb. So the LED night light will have a big power saving for the electricity and money for monthly bill for consumer.
